Consider the number 13. When we divide it by 6, the remainder is 1. Now, what must be added to 13 to make it completely divisible by 6?
12 is completely divisible by 6. We must add 6 more to 12 to make it divisible by 6. While dividing by 13, the remainder is 1. So we add 5 (6-1) more to make the number 13 divisible by 6.
Similarly in this case, we add 2 (23-21).

Consider first 3 digits 105.
23*4=92; 105-92=13.
Now 13 & remaining digit 6 forms 136.
23*5=115; 136-115=21.
If we are adding 2 in 21 then it will completely divisible.
23*4=92; 105-92=13.
Now 13 & remaining digit 6 forms 136.
23*5=115; 136-115=21.
If we are adding 2 in 21 then it will completely divisible.

1056/23 = 45.91.
45*23 = 1035.
Now we can write 1035+23 = 1058.
Hence,
1058-1056 = 2.
45*23 = 1035.
Now we can write 1035+23 = 1058.
Hence,
1058-1056 = 2.

1056/23 = 45.91.
0.91*23 = 20.93 = 21(approx).
23-21 = 2.
0.91*23 = 20.93 = 21(approx).
23-21 = 2.

1056/23 = 45.xx,
45*23 = 1035,
1035+23 = 1058.
Difference between 1056 and 1058 = 2.
45*23 = 1035,
1035+23 = 1058.
Difference between 1056 and 1058 = 2.

I don't understand why we should do 23-21 at the end can anyone explain this. And @Nikitha 2 is not the remainder. 21 is the remainder.

Find digital root for 1056. 1+5+6=12, 1+2= 3 digital root should be less than or equal to one. Digital root for 23 is 2+3=5 so it will of form 3/5 for to exactly divisible we need to add 2 to numerator so answer is 2.
